The UK should be split into green and red zones, with travel across the country being restricted to prevent the spread of coronavirus, according to a leading academic.

Ministers have been told that controls are needed within the country to prevent people from areas with high infection rates creating a second spike in regions such as London, which are effectively managing the infection.

Bary Pradelski, associate professor at the French National Centre for Scientific Research, said that domestic travel controls were just as important as those imposed on people from outside the country.
